Total studying volume (academic lesson/s):
178 academic lessons, of which,
20 academic lesson/s theory,
140 academic lesson/s practice,
14 academic lesson/s Preparation for an exam – visual control,
4 academic lesson/s professional advice.
Methods of teaching: Practical training at an individual welding site consists of performing various tasks of the instructor.

Studying goal: By the end of the training, the welder will be able to weld a wide range of welding products, parts and building structures. For more aptly done work (for products requiring special control), consult with your supervisor, coordinator or master. The welder uses the following welding techniques: TIG-welding (141, 142) и Manual arc welding (MMA 111).

The description of the studying environment: Both theoretical and practical sections will be held at Pae 29, Tallinn. Safety and cleanliness are guaranteed. To study the theory, we have 4 classrooms. Depending on the subject, each class accommodates more than 30 people. The theoretical part is given in-hand (or on memory cards) to strengthen knowledge after the lesson. We also provide both personal protection and work equipment for practical exercises.
List of training materials: WPS if necessary
Release requirements, including assessment methods and assessment criteria: At least 80% of attendance is a prerequisite for completing the training. In addition, the detail must be welded in accordance with WPS and in accordance with the evaluation criteria.
Documents to be issued: The complete certificate if the requirements in obtaining it are met. Certificate of participation if the learning outcomes were not achieved, but the student participated in the study. The certificate is issued depending on the number of hours visited, but not if the student participated in less than half of the lessons.
Summary: The course is intended for workers with metal (who previously studied and worked in metalworking) and who face this type of daily work and need high-quality and accurate welding. The course aims to acquire professional practical knowledge. A student who completed the course will be able to apply the knowledge gained, namely, to weld various materials and details, considering the conduction of his daily duties using tools and welding equipment. After completing the course and passing the final exam, the student is ready to work or take an internship.
Formation of the final result:
Knowledge and the use of professional terminology, successful completion of the practical part of the course
Visual examination by WPS
